The use of drugs to induce anaesthesia and analgesia in the subarachnoid or epidural area is known as neuraxial anaesthesia. It may result in total loss of motor and/or sensory functioning below or above the injection site. Neuraxial anaesthesia doesn't always result in a total loss of motor function; it depends on the anaesthetic’s dose and concentration. When a woman is in active labour, for instance, the aim of neuraxial anaesthesia is to offer analgesia but not to impair her capacity to control her lower extremities.

Spinal, epidural, and combination spinal-epidural anaesthesia are the three most often utilised neuraxial methods. The absence of the necessity for parenteral opioids, which have numerous negative side effects and are linked to issues with the heart, lungs, and kidneys, is one of the main advantages of neuraxial anaesthesia. Additionally, due of improved pain control and shorter hospital stays, perioperative and obstetric pain treatment using neuraxial anaesthesia has increased patient satisfaction levels.

Spinal treatment: A needle is introduced into the ligaments between the vertebrae and a single dose of medicine is injected to deliver spinal neuraxial anaesthesia and/or analgesia.

Implementation of an epidural: A Tuohy needle is used to administer an epidural after it has pierced the ligaments between the vertebrae.

CSE administration involves inserting the needle into the epidural area. There are two steps to CSE anaesthesia. An epidural space is first punctured using a Tuohy needle. A bolus of local anaesthetic is then injected into the subarachnoid space after the spinal needle has been inserted through the Tuohy.

To stop pain signals from reaching the central nervous system, local anaesthetics block sodium channel transmission by soaking the spinal cords nerve roots. Lidocaine, bupivacaine, and ropivacaine are the three local anaesthetics most frequently used for neuraxial anaesthesia. Co-administering opioids like fentanyl, morphine, and hydromorphone with local anaesthetics can have a synergistic effect that reduces the transmission of pain. This type of local anaesthetic administered and whether it is injected once or continuously using an epidural or CSE procedure determine the length of analgesia. Epidural administration produces anaesthesia or analgesia as long as the catheter is in the epidural space as well as a continuous infusion of drug is running. Single spinal injections typically last 60 to 150 minutes depending on the anaesthetic administered.
